I favor higher costs for gas. My hope is it leads to a more realistic valuation of transportation and it's costs.

When importing a 200lb finished wood item from China is still cheaper than making it here, we're not doing it right.

When people think cars and gas and highways and accidents and lost time due to congestion are all less of a burden than public transit, we're doing it wrong.

When we falsely keep the price of fuel below it's current real value, we lose the differentiation it SHOULD make. 

We currently have some of the lowest fuel prices in the world, aside from the producing countries (gulf states, etc).

Think about our commuter habits. Big employers just expect people to drive great distances to them, when they could reasonably set up satellite offices much more effectively. :)
